I notified Dave.
Certainly willing to give Dave a chance to get these right. I still think this is the way to go for the Knight's and BH209. If it was an easy fix... I'm sure Knight would have implemented it !
I especially like the vent liner concept. I'm finding I get under 400 shots out of a T/C Omega breech plug with Fed 209a primers before it starts getting serious erosion... along with blow back. My 25 ACP conversion has 3x that many shots with T7... and still no erosion.
Please fix this Dave.....I'm tired of messing with o-rings and drilling out Knight B/P's.
